 DETAILED DESCRIPTION
The principle of the first preferred embodiment of the present disclosure is described as follows.
A first embodiment relates to a collapsible stroller, which may include a handle tube 1, a front leg tube 2 with a front wheel assembly, a rear leg tube 3 with a rear wheel assembly, a joint assembly 4 connecting the handle tube 1 to the front leg tube 2 and the rear leg tube 3, and a reversible seat 5 reversibly mounted on the joint assembly 4. The reversible seat 5 is provided with an engaging projection 7, and the joint assembly 4 is provided with more than one engaging recess 6.1 and 6.2 rotatable with the stroller frame. The stroller frame can be collapsed after the engaging projection 7 of the reversible seat 5 is inserted into the engaging recess 6.1 or 6.2. The rotating stroller frame brings the reversible seat 5 to rotate therewith, so that the reversible seat 5 is collapsed along with the stroller frame. The details are shown in FIGS. 1-4, 6 and 10.
The joint assembly 4 in the first embodiment is provided with at least two engaging recesses 6.1 and 6.2, wherein one engaging recess 6.1 is provided on a lower joint 4.1 fixedly attached to the front leg tube, and the other engaging recess 6.2 is provided on a joint cover 4.2 fixedly attached to the rear leg tube 3. The details are shown in FIG. 3.
The joint assembly 4 in the first embodiment may include an upper joint 4.3 fixedly attached to the handle tube; the lower joint 4.1 fixedly attached to the front leg tube; the joint cover 4.2 fixedly attached to the rear leg tube 3, wherein the upper joint 4.3 and the lower joint 4.1 can pivot about an axis A and B on the joint cover 4.2 respectively; and a stroller safety lock 8 for controlling the pivoting of the upper joint 4.3 and the lower joint 4.1 about the axis A and B on the joint cover 4.2. The details are shown in FIG. 3.
A backrest portion 5.1 and a seating portion 5.2 of the reversible seat 5 are collapsible. A seat safety lock 5.3 is provided on the reversible seat 5 for controlling the collapsing of the backrest portion 5.1 and the seating portion 5.2. After the release of the seat safety lock 5.3, the backrest portion 5.1 and the seating portion 5.2 can be collapsed. The details are shown in FIGS. 4-5.
The reversible seat 5 in the first embodiment may be mounted in a forward orientation, with the engaging projection 7 inserted into the engaging recess 6.1 on the lower joint 4.1 fixedly attached to the front leg tube 2. Before the collapsing of the stroller frame, the seat safety lock 5.3 on the reversible seat 5 is released and the backrest portion 5.1 and the seating portion 5.2 are collapsed. Then, the stroller frame is collapsed by operating the stroller safety lock 8, and the reversible seat 5 along with the front leg tube 2 approaches the rear leg tube 3. The details are shown in FIGS. 6-9.
The reversible seat 5 in the first embodiment may also be mounted in a rearward orientation, with the engaging projection 7 inserted into the engaging recess 6.2 on the joint cover 4.2 fixedly attached to the rear leg tube 3. Before the collapsing of the stroller frame, the seat safety lock 5.3 on the reversible seat 5 is released and the backrest portion 5.1 and the seating portion 5.2 are collapsed. Then, the stroller frame is collapsed by operating the stroller safety lock 8, and the reversible seat 5 is collapsed along with the rear leg tube 3. The details are shown in FIGS. 10-13.
In the first embodiment, the engaging projection 7 on the reversible seat 5 and the engaging recesses 6.1 and 6.2 are provided with guiding parts respectively having corresponding convex and concave configuration, so as to facilitate the positioning of the engaging projection and the engaging recesses and prevent the erroneous insertion into the engaging recess 6.1 or 6.2 during the reversal mounting of the reversible seat 5.
As the second embodiment of the disclosure, the engaging recess 6.1 for receiving the engaging projection of the reversible seat is provided on the joint fixedly attached to the handle tube 1, and other structures and the principle are similar to those in the first embodiment.
As the third embodiment, before the collapsing of the stroller frame, the backrest portion and the seating portion of the reversible seat need not to be collapsed first, or the backrest portion and the seating portion of the reversible seat are non-collapsible. Other structures and the principle are similar to those in the first embodiment.
As the fourth embodiment of the disclosure, both the upper joint and the lower joint pivot about only one axis on the joint cover. Other structures and the principle are similar to those in the first embodiment.
As the fifth embodiment of the disclosure, the joint assembly may include an upper joint, which is fixedly attached to the handle tube, movably attached to the rear leg tube, and pivotable along with the handle tube about the movable junction on the rear leg tube; a lower joint which is fixedly attached to the front leg tube and is pivotable along with the front leg tube about a movable junction on a seat mount of the stroller frame; and a stroller safety lock for controlling the release of the upper joint and the lower joint. A first engaging recess rotatable with the stroller frame is provided on the lower joint fixedly attached to the front leg tube, and a second engaging recess is provided on the upper joint fixedly attached to the handle tube. The engagement of the engaging projection on the reversible seat and the collapsing principle are similar to those in the first embodiment.
As the sixth embodiment of the disclosure, the joint assembly may include a handle joint movably connecting the handle tube to the front leg tube and the rear leg tube, wherein the handle tube is pivotable about a movable junction on the handle joint, and the front leg tube and the rear leg tube are pivotable about a movable junction on the handle tube and the seat mount of the stroller frame; and a stroller safety lock for controlling the pivoting of the handle tube. A first engaging recess rotatable with the stroller frame is fixed on the upper section of the front leg tube, and a second engaging recess is provided on the handle joint or fixed on the upper section of the rear leg tube. The engagement of the engaging projection on the reversible seat and the collapsing principle are similar to those in the first embodiment.
By way of the six embodiments set forth above, collapsing the stroller frame together with the reversible seat by means of more than one engaging recess falls within the scope of the disclosure, no matter the engaging recess is provided on the joint for collapsing the stroller frame, the front leg tube, the rear leg tube or the handle tube and no matter the backrest portion and the seating portion of the reversible seat are collapsible. As used herein, an element or step recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural elements or steps, unless such exclusion is explicitly recited. Furthermore, references to “one embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features.
The present disclosure is not to be limited in scope by the specific embodiments described herein. Indeed, various other embodiments of and modifications to the present disclosure, in addition to those described herein, will be apparent to those of ordinary skill in the art from the foregoing description and accompanying drawings. These other embodiments and modifications are intended to fall within the scope of the present disclosure.
